BJ-11 Battery Charger

Ricoh BJ-11 Battery Charger — Flexible USB-C Charging for GR III Professional Shooters

The gist: A dedicated USB-C external charger for the Ricoh DB-110 battery — lets professional GR III and GR IIIx photographers keep a spare battery charged via laptop, power bank, or any USB-C source between shoots.

• Charges via any USB-C source: Connect to a laptop, power bank, or USB wall adapter — useful for photographers who work in locations without dedicated camera charging setups, such as coworking spaces or client offices.
• 2.5 hour full charge: Predictable charge cycle that fits into a standard work break — plug in during lunch and have a full DB-110 ready before the afternoon session.
• External charging preserves in-camera USB port: Charging the spare battery externally keeps the GR III’s USB-C port free — important during shoots where you might need the port for tethering or data transfer.
• Compact design matches the GR III philosophy: The BJ-11 is proportionally small — carrying it alongside the GR III doesn’t meaningfully add weight, preserving the compact-system advantage of the GR III setup.

Ricoh’s official product page confirms the BJ-11 charges the DB-110 via USB-C in approximately 2.5 hours, and lists compatibility with the GR III, GR IIIx, GR III HDF, GR IIIx HDF, WG-6, and THETA X camera bodies.

Best for: Ricoh GR III and GR IIIx photographers who carry a spare DB-110 battery and want a dedicated external charger with USB-C flexibility. Skip it if: You own a Ricoh GR IV — the GR IV uses the DB-120 battery and the BJ-12 charger, not the BJ-11. Runs ~$27 — check the current price before buying.
